ATTACHMENT FOR DENTAL ARmcnLATons.

, Application filed June ,1

To all mag concern Be it known that I, JosErH BECKER, a

citizen of the United States. residing at \Vest .Hoboken, in the county of Hudson and State of New Jersey, have invented a certailihew and useful Improvement in Attachments,for Dental Articulators, of Which the followingis a full, clear, and exact dek g V I in shown one vSuch means, same cons st ng scription.

The object of this invention ,is'to provide an attachment for dental articula.t0rs,' by which it s poss ble to reproduce averageor individual-inandibular movements for the purp'oseof enabling the dentist to properly occlude articulate artificial teeth.

Th e itttaChnwHtJS designed for use onany usual or approved dental articulator, and

.while it is illustrated he'rein for use upon a well-known construction of art culator, 1t

is to beunderstoodthat the inventionjs not so limited Moreover, the attachment in oneor the. other of thefforms herein ex- -;pla'in'ed and variations thereof, maybe used in several different'places on an a'rticulator. and makes the articulator adjustable to the differeutimovements of the jaw. A large percentage of failures in dent'alplate, bridge and crown work .i Clue/Ito inability to copy the exact movements of the jaw, but with 'y' invention these movements can be duplicated.

The invention consists of an adjustable device comprising one "or more sectors mounted in a segmental holder'and movable therein as the dental operationlrequires and capableof being fixed in the adjusted-position, and in the case of a device using two such sectors, each sector sad ustab le 1ndependently of the other,." asl will proceed now' to explain and finally claim.

Inthe accompanying drawings illustratingjtheinvention, in the several figures of which like parts are similarly designated, Figure 1 is a perspective view showing'the duplex attachment; Fig. 2 is a longitudinal section thereof, and Fig. 3 is anend elevation. Fig. 4 is a side elevation and Fig. 5 is an end elevation of a single attachment, the block being broken off, all of the views being on an enlarged scale. Fig- 6 is a side elevation illustrating the invention as applied to an articulator inuse. Fig. 7 is a sideelevation illustrating the invention as applied to an articulator, the upper model bowbeing elevated.

and beveled, as shown inFig. 5. The end "of the shell formed by thesideand rim is closed by the block 14, and the near end'of this block may be beveled'to form the sighting edge 20, and thus adapt the instrument 4L and 5' show'sthe-sameprinci'ple applied tofor use as an incisor guide alone or in cooperation with. the first described attach ment. By its use it is possible to obtain a vertical adjustment of the incisor path.

Either or both of the attachments may be a part of or attached to an articulator. Figs. 6 and 7 show such an application of both of the attachments, the duplex attachment being applied to the lower model bow 21 and the single attachment being shown as applied to the upper model bow 22, and these two bows operatively connected through the medium of any suitable back piece or standard herein designated 23, but shown in purely conventional form.

By the use of these attachments the natural movements of individual jaws characteristic of different patients may be accurately ascertained or duplicated and the dentist thus aided in performing his work skillfully. The changing of the condyle,

vlateral and incisor paths or the articulator may be readily effected, and any one or more of the paths mav be changed without in any Way changing the others.

As will be understood, the sectors are not pivotally mounted in their shells, but on the contrary, they are bodily movable in their shells in order to change their adjustments.

Variations other than those described are permissible within the principle of the invention and the claims following; and it is to be expressly understood that by the use of the term attachment I mean to include not only a separable thing but also one that is integral with or fixed to an ar- ,ticulator.

3. An attachment for dental articulators,

; comprising a shell having side-plates and a longitudinally slotted rim, a pair of sectors Lessee? mounted to slide longitudinally in said shell, and means for independently adjusting said sectors as upon an axis and fixing them in said adjustment.

at. An attachment for dental articulators, having a guideway and holder composed of side plates and a connectinglongitudinally slotted arcuate rim, a sector mounted to slide bodily in said guideway and holder and means to fix said sector in adjusted position,

5. An attachment for dental articulators, having a guideway and holder composed of side plates and a connecting longitudinally slotted arcuate rim, a plurality of independent sectors arranged apex for apex in said guideway and holder and each sector independently movable bodily therein, and setscrews for fixing the sectors in adjusted position.

6. An attachment for dental articulators, comprising side-plates, and a longitudinally slotted arcuate rim connecting said sideplates the whole constituting a shell, a sector mounted in said shell and a sector-adjusting device projecting through and movable in the slot in the rim and engaging the sector and rim.

7, An attachment for dental articulators, comprising side-plates, and a longitudinally slotted arcuate rim connecting said sideplates the whole constituting a shell, a sector mounted in said shell and a sector-adj usting device projecting through and movable in the slot in the rim and engaging the sector and rim, and a block attached to the shell and closing one of its ends.

8. An attachment i or'dental articulators,

comprising side-plates, and a longitudinally slotted arcuate rim connecting said side plates the whole constituting ashell, a sector mounted in said shell and a sector-ad justing device projecting through and movable in the slot in the rim and engaging the sector and rim, and a block attached to the shell and closing one of its ends, said block having a beveled end.

In testimony whereof I have hereunto set my hand this 31st day of Ma A. 111922. JOSEP BECKER. Witnesses ARCHIBALD MARTIN, ANNA HIGGINS.
